NICE / APOLLO SPEG019B00A 120V Transformer Group for M-Bar and L-Bar Operators
The Nice Apollo SPEG019B00A transformer group is the 120V power transformer assembly for compatible M-Bar and L-Bar barrier operators. It converts incoming 120 VAC power to the internal voltages used by the barrier operator controls and power circuits. This part is commonly selected for North American M3BAR, M5BAR, M7BAR, and LBAR installations that were built for 120V input. The most important fitment issue is voltage: SPEG019B00A is not the same as the 230V SPEG019A00A transformer group. If a transformer failed from a surge, water intrusion, incorrect wiring, or control-board short, the root cause should be corrected before the new assembly is installed.

Technician Note
If the original transformer failed, inspect the incoming power, grounding, surge protection, and board condition. Replacing the transformer without correcting the cause may lead to repeat damage.
Before Ordering
- Confirm site input voltage is 120V.
- Confirm the installed operator is an M3BAR, M5BAR, M7BAR, or LBAR model.
- Match the original transformer group number.
- Check for water intrusion, surge damage, and wiring faults.
- Use a qualified technician for line-voltage electrical work.
Professional Advisory
Transformer replacement involves line voltage. Disconnect power and follow manufacturer service procedures. Do not attempt electrical repair if you are not qualified.
Important Ordering Warnings
- Do not install SPEG019B00A on a 230V operator. Use SPEG019A00A for 230V applications when specified.
Product Questions & Answers
What is SPEG019B00A?
SPEG019B00A is the 120V transformer group assembly for compatible Nice Apollo M-Bar and L-Bar barrier operators.
Which operators commonly use it?
It is commonly associated with M3BAR, M5BAR, M7BAR, and LBAR barrier operator families configured for 120V input.
Is it interchangeable with SPEG019A00A?
No. SPEG019B00A is the 120V version and SPEG019A00A is the 230V version.
What happens if the wrong voltage transformer is used?
The wrong transformer can damage the control system, create incorrect output voltage, and cause an unsafe electrical condition.
What should be checked first?
Confirm site voltage, operator model, original transformer label, wiring, and any related surge or board damage.
